To all whom it may concern:

Be it known that we, -HOWARD SAMUELS and Bonner Biueos, citizens of the United States, residing at Delhi, in the county of 6 Delaware and State of New York, have invented certain new and useful Improvements in a Nonskid Device; and we do hereby declare the following to be a full, clear,

and exact description of the invention, such in as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to new and useful improvements in nonskid devices for either pneumatic or solid tires and has for its primary object the provision of spaced hare or members connected to the usual side chains and being curved to conform to the transverse curvature of a tire having calks cc to bite into the ground for giving the tire the desired traction and preventiskidding thereof, and also said members having the calks removable therefrom whereby any one of the calks when worn or broken may be easily and quickly detached and substituted by a new one,

Another object of this invention is the provision or" nonskid devices of the above stated character which will be simple, durable and efi'icient, and which may be manu factured and sold at a comparatively low cost.

With these and other objects in View as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will he hereinafter more fully described and claimed.

40 For a complete understanding of our invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary side elevation, illustrating a non-skid device constructed in accordance with our invention and showing the same applied to a tire,

Figure 2 is an edge view, illustrating one of the non-skid members, a Figure 3 is a detail sectional view, illusopenings formed in ,aas.

trating the connection hetwecn the member and the calks,

Figure l is a perspective view, illustratmg a modified form of our invention and applied to a solid tire, a

Figure 5 is a similar view, illustrating another modified form of our invention,

Figure 61 another modified form of our invention applied to a double tread solid tire.

Referring in detail to the drawings, the numeral 1 indicates an entirety a non skid device which includes usual side chains 2 to which are secured our improved non-skid element 3 and the latter each includes a curved her or member l adapted to extend transvers y and snugly fit the tread of a tire is provided at its ends with openings to receive short chain sections 5 to which are secured fastening links 6 in the form of hcoks that engage in the links of the side chains and have their hook portions bent into engagement with their major portion to firmly the member l to the side chains, The fastening members 6 are arranged in pairs and fastening members of each pair diverge and are fastened or secured to spaced links of the side chains. The member 4 is constructed from fiat material and has secured to its outer face callrs '5 that have screw threaded shanks 8 adapted to he threaded into screw threaded the member 4r. The calks are adapted to bite intothe ground for the purpose of giving the tire to which the device is applied the desired traction and consequently prevent skidding.

Referring to our modified form of invention shown in Figure 4, the bar or member 8 comprises a straight portion 9 with inclined diverging portions 10 consequently forming the member 8 of a shape to fit the tread portion of a solid tire 10. The ends of the inclined portions 10 are provided with openings to receive short chain sections 12 to which the fastening elements 13 are secured. The modified form of invention, shown in Figure 5 is similar to the form 'ust described except that a greater numer of calks 14; are employed. The purpose is a similar view, illustrating 4 of using the greater number of calks is to increase the traction containing qualities of the device and also when the device is constructed to grip larger size tires it is desirable to increase the number of calks. Referring to our modified form of invention shown in Figure 6, the bar or member intermediate its ends is offset to forma V-shaped portion 16 adapted to fit within the annular groove 17 formed between the tread portions 18 of a double tread tire 19.

The bar or member 15 is rovided with the inclined portions 20 to w ich the fastening elements 21 are secured. Sometimes it is desirable to employ chains to pass about the spokes and fasten to the-elements 21 in- 5 1s to be understood that minor changes in of parts may construction, combination and arrangement be made without de arting from the spirit and scope of the following claim.

Having thus described the invention, what we claim is An anti-skid device comprising a bar, said bar bent to provide 'a V-shaped inwardly deflected portion midway its length, said V-shaped ortion adapted to fit snugly within the V-s aped groove in the tread of a double tread tire, traction lugs carried by the portions of the bar intermediate the V-shaped portion and the ends of the bar, and said bar having its end portions inwardly and laterally inclined to snugly engage the inclined edges of the tire.

In testimony whereof we aflix our signatures in presence of two witnesses.
